COURSE DESCRIPTION:

This 3-day NHI training course 130093A entitled "Displacement-Based Seismic Analysis and Design of Bridges" is a shortened version of the 5-day NHI 130093 Course "LRFD Seismic Analysis and Design of Bridges" focusing specifically on the displacement-based design philosophies. It is a comprehensive and practical training course that addresses the requirements and recommendations of the seismic provisions in the AASHTO Guide Specifications for LRFD Seismic Bridge Design.

The 130093A course reviews the fundamental principles of seismic design including engineering seismology, structural dynamics (SDOF and MDOF), seismic and geotechnical hazards, and methods for modeling and analyzing bridges subject to earthquake ground motions. The 130093A course then discusses the principles and applications of capacity design to piers, foundations, superstructures and connections, and a brief introduction to the principles and some application of seismic isolation.

The course is accompanied by a prerequisite Web-based Training (WBT) 130093W Course "Introduction to Earthquake Engineering". The participants are highly recommended to complete the WBT course prior to the Instructor Led course. The WBT prerequisite course consists of 5 lessons including Introduction to Earthquake Seismology (L1); Damages to Bridges due to Strong Motion (L2); Single Degree of Freedom (SDOF) Systems and Response Spectra (L3); AASHTO Design Ground Motion Characterization (L4); and Introduction to Geotechnical Hazards (L5).

OUTCOMES:

Upon completion of the course, participants will be able to:

Identify types of bridge damage to avoid

Use acceleration and displacement response spectra to estimate peak forces and displacements

Describe the relationship between detailing of transverse steel and ductility demand on a column

Develop the design overstrength forces for a column

Explain how liquefaction affects the seismic design process

Describe strategies for protecting superstructures from damage

Compute required support lengths in accordance with AASHTO design specifications

Describe common processes embedded in both the LS and GS

List the four seismic design categories in the GS and the key requirements for each category

Describe the basic purpose of seismic isolation

TARGET AUDIENCE:

This course is intended to engage a target audience of bridge engineers with zero and up to 20 years of experience, through instructor-led presentations, discussions, Q&A, group activities, walkthrough examples, and hands-on student exercises and design example practices.
